My invention relates to holding molding for use in the application of wall and ceiling board panels or the like, the particular embodiments hereinafter to be described being especially adapted for fast application of such panel board.

The princi al object of my invention is to provide meta lie molding formed-from sheet metal and substantially T-shaped in crosssection.

' An important object is to provide such T- shaped molding with holes for the fastening means at spaced intervals along the median line thereof and pockets for such fastening means formed in the leg of the T to receive the fastening means and to prevent displacement thereof.

Ai'further ob'ect i -to effect economy in the time and la or required in the application of the panels and to facilitate the handling thereof.

Another object is to provide apanel holding molding adapted to be nailed or otherwise secured to the post or joist members or walls of a building and having resilient side portions overlapping and bearing upon the edges of adjacent panels tosecure them in position. firmly and without the use of nails and like fastening devices in the panel area Other objects and advantages will appear from an inspection of the'drawings in which 10 represents the blank piece of metal from which the molding is formed. The nail holes 11 are punched and the nail pocket depressions 12 on opposite sides of holes 11 are pressed in the blank rior to the shaping operation. punching and nail pocket pressing operations on the blank piece as shown in Figs.

1 and 2, the piece is folded along its lonitudinal median line and portions thereof ent outwardly to form a section of general T configuration. With the piece shaped as Upon comp etion of the hole described the nail pocket depressions 12 will complement each other to form nail ockets 13 having direct communication with the holesv 11. The'pockets may be shaped to the contour of any standard or special type nail,

those of the drawings being shaped to accommodate a common form of finishing nail 14. Thus formed the nail pockets'pro vide extended gri ping contact between nails and molding or the full depth of the molding strip. This extended contact holds the nails against dis lacement and insures a rigid alinement of t e nails with the molding strip the pockets forming guides to prevent de ection of the nails while entering the holes 11 during the nail driving operation.

The outwardly extending portions 15 of the molding overlap the edges of adjacent boards 16 as illustrated in Figs. 5 and 6 and are downwardly pitched to insure a firm bearing on the panels. The central leg portions in tion 17 of the T-section is preferably shorter than the thickness'of the panels 16 to permit the flanges 15 to first bear upon the surface is rendered possible because of the resiliency of the flan es 15 which yield to slight variatfie anels and provide extended engagement t rou bout the length of the mold ng the edges of the panels with a continuous and firm-bearing regardless of possible mequalities in the cutting and fitting of the boards. This flexibility of the bearing contact also permits expansion and contraction of the boards due to temperature variations. The nails holdingthe molding do not pass through the panels held by it but leave the panels free to adjust themselves to the weaving and racking movements of the framing members or wall to which the molding is secured.

A modified form of the molding is shown in Figs. 9 and 10 in which the molding face 18 is prof'ected outwardly from the plane of the pane s 16 to produce a more pronounced paneling effect, should that be desired to meet the requirements of appearance and finish. This is accomplished by a slight change in I the contour of the molding involving the miration. This type of raised molding .is, in

allother respects, similar to the molding shown in Figs. 3 to 8 inclusive and 'in the matter of the initial downward pitch of the flange portions 15 and in the resiliency of said flanges for the purpose hereinbefore de scribed.

The raised type of molding is desirable for use in decorative schemes in which the boards are exposed, but when theboards are to be covered by Wall paper, burlap, or other covering, a smooth surface unbroken by protruding areas is essential. This may beachieved by; depressing the faces of the boards along t eir edges so that the molding flange faces will be flush with the board faces, the whole presenting a plane surface permitting the application of any desired wall covering.

The moldin shown in Figs. 3 to 8 inclusive may be a apted to corner construction, either to inside corner treatment as shown and firm y and securely hold the panels 1n position. The flanges 15 overlap mages:

in Figs. 11 to 14 inclusive, or toexposed corner application as shown in Figs. 15 and 16. 'In the application of any of the forms of corner arrangement referred to, the characteristics of the molding are retained. The corner construction shownin Figs. 11 and 12 involves the use of two juxtaposed molding ieces having their'contiguous flanges veled as at and their body portions at right angles to each other, the outer flanges .15 bearing upon the board 16 as shown in Fig. 12 while the beveled'flanges 20 rest with their ed es against the framing or wall of the buil ing and are held against displacement by the nails 14 in the'pockets 13 of the respective'moldings 10 after the fashion obtaining in theapplication of moldings away 4 from corners. y

Preferably I employ corner molding in ofie piece as shown in Fi .13 to 16 inclusive. The molding is of doub e T formation bent along its median line'to presenttwo faces at -right. angles to each other, each face representing a molding havingall of the characteristios of the separately formed pieces, the

- only diflerence 'being that the inner or contiguous flanges 15 are connected. In both forms the -nails 14 are driven at right angles to each other as shown in these figures, the pockets 13 of the respective sides of the molding for exposed corners being relatively staggered as shown in Fig. 15

to avoid possible interference on the part of the nails 14 of one section with those of the companion section durin the nail driving operation. The connect flange portions of the corner moldings are interdependent as will be obvious since any movement of one of said flanges 15 is resisted by the contiguous flange 1501f the companion molding thereby mutually reinforcing each other against displacement.

From the foregoing it is apparent the use of the invention-will effect an appreciable saving of time and labor since but one row of nails is required to hold the molding and both panels. The driving of nails through the panels is dis need with. The molding section insures t e maximum strength and rigidity, is fireproof, and'may be finished to coniorm to any desired decorative scheme. The desi n is ideal for temporary construction, an both molding and ,panel boards may be salvaged without damage to either for use elsewhere- The word wall-board is used in its broadest sense to include also ceiling boards. 1

What I claim is-:-

1. A wall assembly comprisin a pair of wall boards spaced apart, a ho ding moldng of general T formation arranged with its depending le portion in the space between said oar s and its oppositel ex tending flanges downwardly itche and overlying the adjacent edges 0 the boards,

III

sume another and final position on said.

' boards upon consummation of the assembling operation, and securing means for said molding andboards passing through said molding only. 7

2. In a panel-board arrangement comprising panels spaced apart, holding molding between the panels having .resilient flanges overlapping adjacent edges of said panels,

. said flanges being downwardly pitched'dur ing the initial stages .of the assembling operation and adapted to yieldto assume another and final position onsaid panels upon and summation of the assembling operation,

I fastening devices passing through said molding on1y.,

3. In a wall-board assembly, a pressed metal panel-holdingrmolding having a crosssection of general configuration, securing means inthe depending flange'portion thereof, and resilient outwardly extending, downwardl pitched flanges on opposite sides of said epending flange portion overlapping contiguous edges of the panels, said depending flange portion comprising a pair of web plates joined at their lower edges and connected at their 11 per margins to said downwardly itched anges. v

4. The com ination in a wall-board assembly having panels spaced apart, of a pressed metalpanel-holding molding made by folding a piece of metal-along its longitudinal Vsald pane s, the upper median line to form a'leg portion depending between and of less depth'than said panels,

'the upper portions of the webs of said depending leg, portion'being turned outwardly and pitched downwardly to overlap andengage contiguous mar s of the panels. I

5. In a wall-boar assembly, a pressed metal panel-holdin molding having a crosssection of general r configuration, resilient outwardly extending, downwardly pitched flanges on' opposite sides of the depending flange portion of'said molding overlapping and engaging contiguous margins of the panels, and securing means in said dependmg'flange portion and between said pitched flanges.

6. The combination in a wall-board assembly having panels spaced apart, of a pressed metal panel-holding molding made by folding aipiece of metal alon its longitudinal median line to form a Iegportion dependin between and of less depth than portions of the webs of said depending portion being turned outwardly and pitched downwardly to overlap and engage contiguous margins of the panels, and securing means between said webs and flanges, said webs and flanges being spaced apart at intervals to provlde extended engagement with said securing means.

In witness whereof I have hereunto set myhand.
